Soprani.ca is a collection of projects that aims to replace the entire cell phone network (its radio portions, its telephone network portions, etc.) with freedom-respecting alternatives - the title tries to encompass all of this, but perhaps that wasn't clear. To hopefully clarify a bit, here are the two main Soprani.ca projects right now:

JMP - A gateway to the phone network (including complete SMS support and MMS picture messaging) that you can use entirely over the Internet without involving any sort of cell carrier (and can thus use without anyone tracking your location). You can use JMP right now, and if you find wifi coverage is fine for you, you can ditch your cell carrier altogether and just use JMP for all your text/picture messaging and calling, leaving all the unwanted tracking behind.

WOM - A community-run radio network that lets you send text and picture messages over long distances (several or several dozen kilometres, depending on conditions). You can send your JMP messages over WOM if you like, which gives you cell network-like range, but without the cell network-like location tracking. We are still developing prototypes for WOM - if you'd like to know when WOM gateways (nodes connecting the WOM mesh to the Internet) are ready to deploy, please join the WOM Operatives list.

For cryptocurrencies, we currently only support Bitcoin (you can arrange Bitcoin payment by messaging me privately). We are considering adding others.

No, we do not respond to NSLs. Since all of JMP's own infrastructure is located in Canada, we have no obligation to do so. However, JMP's carrier is largely based in the US (necessarily if you have a US number) so they might respond to NSLs.

I'm Denver, "the programmer behind Soprani.ca", and specifically JMP. Feel free to ask me any questions about JMP, WOM, or Soprani.ca as a whole that haven't been answered in the comments section yet. I'd be happy to hear from you.
